User Manual of Intelligent Programmable Cell Phone Jammer

User Manual Guide

The rate of students in the middle school and university owning the cell phone has been increasing recently as the cell phone has been widely used. It is the common occurrence that students use the cell phone in class, which greatly influences the class rule and teaching quality. Some students even use the cell phone in the examination room for cheating and then the cell phone becomes the cheating tool.

The intelligent programmable cell phone jammer is another new type of cell phone jammer  presented by our company following the cell phone jammer specific for the examination room, whose main function is as follows：the user can program through the micro-computer setter by himself/herself and the program can be transmitted to the main machine of the jammer by the far-infrared communication so that main machine of the jammer can automatically run according to the switching time set by the program.

4. Installation and Use Description of Cell Phone Jammer

4.1 Installation Procedure and Use Description of Cell Phone Jammer

(1) Take out the main machine of jammer of the package and hang it on the wall near the window and the installation height should be more than 2 meters (which is hard for students to touch).

(2) Switch on the 220V power supply.

(3) Transmit the program (see the detailed programming method in working instruction of micro-computer setter) made by the micro-computer setter to the main machine of jammer.

(4) The main machine of jammer starts to automatically run.

(5) The main machine of jammer will indicate the right time during normal work, otherwise it means it doesn’t work normally. If so, immediately cut off the power supply and contact us.
